Comparison of Body Mass Index, Waist Circumference, and Waist/Hip Ratio in Predicting Incident Diabetes: A Meta-Analysis
Key result
Body mass index, waist circumference, and waist/hip ratio showed similar associations with incident diabetes, with pooled relative risks of 1.87, 1.87, and 1.88 per standard deviation increase.
Why the study?
Do body mass index, waist circumference, and waist/hip ratio have different associations with incident diabetes?
Population
32 published studies from 1966 to 2004 evaluating incident diabetes
Comparison

Implication
Similar associations support BMI alone for diabetes risk prediction; leaves open whether central measures add value in subgroups.

Main Result
Effect estimate: RR 1.87 (BMI), RR 1.87 (WC), RR 1.88 (WHR) (95% CI 1.67-2.10 (BMI), 1.58-2.20 (WC), 1.61-2.19 (WHR))
Body mass index, waist circumference, and waist/hip ratio have similar associations with incident diabetes, suggesting no clear predictive advantage of central over general obesity indicators.
Cite This Study
Vázquez et al. (2007) conducted a meta-analysis in Type 2 diabetes. Body mass index, waist circumference, and waist/hip ratio was evaluated on Incident diabetes (RR 1.87 (BMI), RR 1.87 (WC), RR 1.88 (WHR), 95% CI 1.67-2.10 (BMI), 1.58-2.20 (WC), 1.61-2.19 (WHR)). Body mass index, waist circumference, and waist/hip ratio showed similar associations with incident diabetes, with pooled relative risks of 1.87, 1.87, and 1.88 per standard deviation increase.
